Mouse cursor lost when unlocking with Intel graphics

[Kenneth Zadeck]

[Relevant details]
This bug also affects Trusty and all distributions based on it, like Elementary OS Freya.

[Impact]
Mouse cursor is no longer visible after VT-switch for systems with Intel graphics.

Switching VTs again may cause the cursor to become visible again.
- Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7)

This is often observed in systems that lock the session and return to the greeter (including at least Xubuntu, Ubuntu Mate, and elementary OS).

[Test Case]
(Requires a lightdm-based screen locking solution)
1. Start a new session.
2. Lock your screen.
2a. You are redirected to the lightdm greeter.
3. Login/Unlock your session.
4. Cursor is no longer visible.

[Regression Potential]
remains to be seen

===

[Original Report]
Cursor is visible at unlock screen either after returning from suspend or just locking.

After unlocking screen cursor is invisible.

Changing to vt1 then back to vt7 (ctrl+alt+f1 then ctrl+alt+f7) cursor returns

====================

no matter if you suspend or sleep, to swap or disk when you return from it, the mouse cursor is missing. you can still move the mouse and you can see (because it highlights the window) as you move it around. But the cursor is not displayed on the screen.

i am using a lenovo W540 laptop. I downloaded the latest beta on april 8 2016.

this is xubuntu using the xfce window manager.

the cursor does return if i log off and log back in, but that actually defeats the purpose of going to sleep.

dmesg and Xorg.0.log

I am a Gentoo user and have the exact same problem as a Debian user which he describes at [1]. His words:

"The mouse pointer simply disappears when I want to log into the system after
locking the screen. After restarting the Xserver, everything backs to normal,
but when I lock the screen again, I won't see the pointer after login. I'm
using lightdm as DM.

I can get the mouse pointer back also when I switch to TTY using ctl-alt-f1 and
then to xsession via ctrl-alt-f7."

The issue appeared between 1.18.1 and 1.18.2, so I bisected. Reverting commit b04767c84deafc44993723add4b1c5163fc11711 by Michel Dänzer solves this particular issue.

Thanks.

Does this also happen using the modesetting driver instead of the intel driver?

Good catch. I tried and it does not happen with the modesetting driver.

can anyone affected check that a switch to vt1 and back to vt7 brings cursor back

[Dan Streetman (ddstreet)]

> can anyone affected check that a switch to vt1 and back to vt7 brings cursor back

yep, that does restore the pointer cursor, at least on my system.

[Dan Streetman (ddstreet)]

this happens even without suspending; I can just close my laptop (which is set to only lock screen), and when I open it and unlock, the pointer is not visible (except the lock screen, where the pointer is visible).

in my Xorg.0.log, the screen lock/unlock logs:
[ 5359.220] (II) intel(0): switch to mode 1024x768@60.0 on LVDS1 using pipe 0, position (0, 0), rot

while the vt switch to VT1 then back to VT7 logs:

To add to the previous comment, running xf86-video-intel/tools/cursor when the pointer is invisible prints a correct pointer image and dimensions.

[Daniel Kessel (dkessel)]

Does not only affect standby/resume. Also happens when locking/unlocking the screen.

[sudodus (nio-wiklund)]

I have this issue or very similar in two laptops, a Toshiba and a Lenovo

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

https://shop.lenovo.com/ISS_Static/ww/wci/products/us/laptop/thinkpad/x-series/x131e-intel/X131e-Datasheet-Intel.pdf

when running systems installed from the Lubuntu alternate iso file. But since my computers are not affected in live mode and not when created from the Lubuntu desktop iso files, I suspect that it is another issue and I will create a separate bug report.

[Paul White (paulw2u)]

Two points to note:

1) I can confirm that just locking the screen on a Toshiba C-50B causes the mouse pointer to not appear when unlocking.
2) I've never experienced this bug during a "live" session and I *have* tried several times.

[sudodus (nio-wiklund)]

It might be the same bug, but I'm not sure. It is strange, that it only affects systems made from Lubuntu Xenial Alternate, not from Lubuntu Xenial desktop.

So I created the bug report

Facing the same issue on Lubuntu 16.04 - 32 bit after upgrading from lubuntu 15.10. The issue seems to be with Light DM, Light Locker setting also not opening.

[Petr Gladkikh (petrglad)]

I have similar issue on Lenovo B50-70 with AMD/Intel graphics, Xubuntu.
Switching to text console and back to Ctrl+Alt+F7 does restore cursor.
I have also noted that
1. Disabling discrete AMD card in BIOS this issue still persists.
2. After waking from lock/suspend there is cursor in unlock screen but cursor disappears after session is unlocked

I just got rid of this problem on 2 laptops by reconfiguring the displaymanager to gdm and back to lightdm

These are the steps it took:

1. sudo apt-get install gdm
2. sudo dpkg-reconfigure lightdm, choose gdm3 here and reboot
3. To get a login screen I had to do CTRL ALT F1 and CTRL ALT F7
4. After login the mouse cursor is also missing, CTRL+ALT F1, CTRL+ALT F7 -> its there
5. sudo dpkg-reconfigure lightdm, choose lightdm, reboot
6. login, go to STR and wake up, mouse cursor is there

Can anyone confirm this?

I tried, as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=815135#30 mentioned, to set accelmethod to uxa, but to no avail. Both vt-switching and xset dpms force off bring back the cursor (where locking removes it).

This is very annoying – what package can I downgrade to avoid the problem more permanently?

[Saurav (saurav1)]

One workaround is to use gnome-screensaver instead of light-locker.

[Leonard Samuelson (len-samuelson)]

Happens with an Intel NUC-5i5RYH (Core i5-5250U), Xubuntu 16.04, DisplayPort driving Acer 2560x1440 monitor.

Another workaround: Create a keyboard shortcut to "light-locker-command --activate". I use "ctrl-alt-C". Using the command "xset s activate" also works. When an unlock fails to restore the mouse cursor, using the keyboard shortcut flashes the screen and when reactivated the mouse cursor is visible.

[Jose Bordelon (jose-w)]

I have exactly the same issue with Lubuntu 16.04 with LXDE destop and a Dell Latitude E6500.

[studoret (studoret)]

Happens with shuttle XH170, Intel i36100 , Ubuntu Studio 16.04 LTS

Another workaround, using one keyboard shortcut acting as CTRL-ALT-F1 / CTRL-ALT-F7 sequence :

- create a script with the following lines :

   #!/bin/sh
   sudo /bin/chvt 1
   sudo /bin/chvt 7

- add a keyboard shortcut to this script

- add permission in /etc/sudoers
   <USER> <HOSTNAME> = NOPASSWD: /bin/chvt

[palmerito0 (sandiegobutterflies)]

Would it be possible to automatically run the script in #40 at login?

[studoret (studoret)]

I also wish I had the script called at unlock time, but I have not yet found the way to do that.

[Kevin Brubeck Unhammer (unhammer)]

For those on XFCE, gnome-screensaver won't lock on idle – it requires gnome-session running in order to do that: https://bugzilla.xfce.org/show_bug.cgi?id=5927

A more permanent "solution" for XFCE users is to

 sudo apt-get purge light-locker
 sudo apt-get install xscreensaver
 # To make the "switch users" button know that you use lightdm:
 echo 'xscreensaver.newLoginCommand: dm-tool switch-to-greeter' >> ~/.Xresources

The downside is that you have to enter your password twice when you do "switch users" to an already logged-in user.

[palmerito0 (sandiegobutterflies)]

I placed this script and made it executable in /lib/systemd/system-sleep

#!/bin/sh

# Script to switch between virtual consoles on wakeup to make
# cursor reappear.

sudo /bin/chvt 1
sudo /bin/chvt 7

It doesn't seem to be working. I'll keep investigating to see if there is another place where this script could be put in order to make it execute. The correct place would probably be not on wakeup, but rather on login after wakeup.

[Mrinmoy Dey (mrinmoy1988)]

Simply pressing ctrl+F7 is bringing it back for me

[Jarno Suni (jarnos)]

As for #43, you have to log out and log in before the "New Login" button works in xscreensaver. You do not need to give password twice: first time you can skip it by Ctrl-Alt-F7.

[Jarno Suni (jarnos)]

As for #43 still, if you use other locker than light-locker and switch user using an Action button in xfce4-panel, you can switch back without giving password (by pressing Ctrl-Alt-F7). So it is better to use a script "xflock4 && dm-tool switch-to-greeter" for switching user, if you do not use light-locker. Besides, xscreensaver does not let you unlock a guest session, since it takes null password as cancel. Customize your guest session to not lock on suspend, not to autostart xscreensaver, and to have the ~/.Xresources customization for it, too. (https://help.ubuntu.com/community/CustomizeGuestSession)

BTW. you can not unlock guest session even if you use light-locker.

[Jarno Suni (jarnos)]

Actually, you don't need the ~/.Xresources customization in guest session if you don't start xscreensaver in guest session.

[hyperboria (reganyway)]

why script?
the only command:

xset s activate

helps to return cursor for me, besides the ctrl+alt+f1 ctrl+alt+f7

[Jarno Suni (jarnos)]

hyperboria, you need to use the script, if you use another locker than light-locker. Is activating screensaver by "xset s activate" desired?

[hyperboria (reganyway)]

Jarno, sorry i dont use screensaver. but i supose light-locker is working in my system.

[Angelo (amsgomes-t)]

Desktop computer, Lubuntu just upgraded yesterday and since them the same problem occurs here. The video is a INTEL one.

[Pradyumna (pradyumnarn)]

This is the same issue for me to.. I am using Lubuntu 16.04 LTS.. I do have a workaround which does work

One workaround until a fix is released seems to be to hit Ctrl+Alt+F1 then Ctrl+Alt+F7.

A Debian user reported that running xset dpms force off and then hitting a key also worked.

[Aaron Raimist (aaronraimist)]

I have a external monitor attached to my laptop and the mouse comes back if you move it on to the second monitor. At that point it is fixed until you lock Xubuntu again. Not sure if this is useful information to developers working on the fix but there you go.

What is the status on this bug? Do we know what change caused this issue?

[Aaron Raimist (aaronraimist)]

flocculant has determined (and I can confirm) that setting the Intel drivers to uxa acceleration mode instead of the default sna mode, fixes this issue. This post shows you how to change that option: https://askubuntu.com/questions/225356/how-can-i-enable-the-sna-acceleration-method-for-intel-cards-under-ubuntu-12-04

[Bill Naylor (willnay98)]

Hi,

Thank you so much Aaron!! I reported this bug in Ubuntu Mate and your fix
worked for me. In a nutshell I ran these 2 commands:

sudo mkdir /etc/X11/xorg.conf.d/
echo -e 'Section "Device"\n Identifier "Card0"\n Driver "Intel"\n
Option "AccelMethod" "uxa"\nEndSection' | sudo tee
/etc/X11/xorg.conf.d/20-intel.conf

[palmerito0 (sandiegobutterflies)]

The workaround detailed in #56 did not work for me.

[Yann Salmon (yannsalmon)]

I tried the workaround in #56 but to no avail. Which is consistent with the fact that SNA is the default setting, if the question linked in #55 is correct.

[Olexii (noise2003)]

I can confirm that all workarounds listed in this thread works for me.
- Ctrl+Alt+F1 and then Alt+F7
- xset s activate
- and the most convenient is to switch AccelMethod into uxa mode, as described in #56

[Ernst Kloppenburg (ernst-kloppenburg)]

A few workarounds have been collected here now, which is very helpful.

Can anybody comment on insight about _causes_ for this problem (regression)?
Does anybody know about work on a fix (upstream, in ubuntu)? Strangely, this bug is still in status unassigned.

[palmerito0 (sandiegobutterflies)]

I retract my statement in #58. The workaround in #56 does seem to have fixed the issue.

Adding this in case it helps identifying what is going on.

Here is the upper part of a screen capture. The red dot is the position of the mouse cursor at the time of the capture. Notice how the "g"s above the y-position of the cursor have a glitch, but not the one below. This happens systematically in Thunderbird and updates as the mouse cursor moves (there is a form of hysteresis : when the mouse cursor moves down, a line is affected after the cursor has passed the line below it ; when moving up, the glitch ceases for a given line only when the cursor reaches it).

Hi,

[Peter Ries (peterriesde)]

Turning off "Lock screen" option when suspending worked for me, but I'll try Aarons fix, too. This is more secure ;)

[Scott Garman (sgarman)]

In some A/B testing I've done, changing the AccelMethod to uxa has some unwelcome side effects, including making some browser-based video unusable. For my test case I would just go to the home page of bluejeans.com (a videoconferencing site) with Firefox, and my browser would immediately lock up with the full-page video they display. After removing the uxa setting and restarting my desktop session, it runs smoothly. Just FYI.

[Sami Senng (samiseng)]

With single display ctrl-alt-f1, ctrl-f7 works, with dual display configuration mouse pointer appears on the second display, but on the way back to the first one it completely freezes the whole OS (no logs, only hard reset helps). No matter if I use ubuntu-desktop or lubuntu-desktop.

[Olexii (noise2003)]

Scott Garman (#82) pointed performance regress when AccelMethod switched from sna to uxa. I can confirm, "gtkperf" is almost twice slower with uxa. So is there any way to execute some script at unlock? It would be suitable to execute "xset s activate" automatically as a temporarily workaround.

[Jarno Suni (jarnos)]

Noise, there is no answer for light-locker so far: http://unix.stackexchange.com/q/203339/111181

[unrud (unrud)]

@: logind publishes session changes (including lock and unlock) over DBus.

The following sh-script automatically runs "xset s activate && xset s reset" every time the session is changed and makes the mouse cursor visible again:

dbus-monitor --system "type='signal',sender='org.freedesktop.login1',path='/org/freedesktop/login1/seat/seat0',interface='org.freedesktop.DBus.Properties',member='PropertiesChanged'" | grep --line-buffered "ActiveSession" | while read line; do xset s activate && xset s reset; done

[Saurav (saurav1)]

@unrud: Your script causes the screen to get re-locked on the first attempt at unlocking, but it unlocks and the mouse pointer shows up on the second attempt.

[unrud (unrud)]

@saurav1: Only tested the script on freshly installed Xubuntu 16.04. The screen doesn't get relocked on my computer.

Maybe it's a race condition and setting "Delay after locking screen saver for" in "XFCE Power Manager" under the "Security" tab to a higher value helps.

[Saurav (saurav1)]

@unrud: Your hunch was right. Increasing the delay (even to 2 seconds is enough) resolves the issue. Even on your fresh installation, do check if it works correctly with suspend/hibernate as well when the delay is not more than one second.

I have gone back to gnome-screensaver for the time being, however, because my Wi-Fi keeps going off after resuming from more than one consecutive (with no intervening normal reboot) suspend/hibernate states with light-locker (I don't know why).

[Jose Bordelon (jose-w)]

I'm affected by this bug too. Dell Latitude E6500 after upgrade from Lubuntu 14.04 desktop AMD64 to Lubuntu 16.04. Cursor dissapear and when I press Ctr-Alt-F1 and return with Ctr-Alt-F7 cursor is visible again.

For those using Intel integrated chipsets, you can use UXA (instead of SNA) acceleration method as a workaround:

[Andrew Lucas (apl270592)]

Hi all,

I've been running Xubuntu 16.04 since about Feb 2016, and this has been an issue for ages.

Prior to seeing the fix for Ctrl+Alt+F1 -> Ctrl+Alt+F7 (which works), the fix for me was navigating to Chrome web browser, logging into Netflix, and playing a video. I've no idea why, and I'm not proposing this as a fix for anyone (clearly the above combination is quicker/easier), but I'm hoping it might help pin down the cause.

I don't have the technical skills to contribute a patch myself, but I was prompted to comment because I'm a bit worried that we're over a month past a release and seeing this bug - which has been around for 2/3 months before release - on an LTS, and still we don't even have it assigned.

[Ezekiel Thiessen (ezekielthiessen7)]

Hey,
I'm running Xubuntu 16.04 64-bit on an older HP Compaq dc7900 computer with a Core 2 Duo E6500 2.33GHz Processor and the Intel Q45 Graphics chipset and I am encountering the same problem. Pressing Ctrl+Alt+F1 and Ctrl+Alt+F7 rectifies the problem.

I am on a MacBook Pro Retina - and I guess this is the Intel graphics card I have:

Hoping for a fix but in the meantime, here is a way to automate the workaround:

https://linux4tw.wordpress.com/2016/05/25/disappearing-mouse-pointer-in-xubuntu/

Thanks to studoret for the idea!

[4X_Pro (adoi3)]

The same bug exists in Lubuntu 16.04 on my ASUS notebook with dual cards: Intel HD Graphics and NVidia. After I have switched to UXA acceleration like described in #95, the problem has gone.

[studoret (studoret)]

Hi,

Good job da_coynul.
I'm pleased to read that you succeed to automate the chvt based script.
Your solution works when I lock/unlock my PC, but not when the PC is locked by idle time.
Anyway, I prefer to keep your workaround with the Ctrl+c shortcut and set back the sna acceleration mode.

[AroundWorker (aroundworker)]

Best workaround:

* purge package `light-locker`

* install package `i3lock`

* execute command: `sudo ln -s /usr/bin/i3lock /usr/bin/slock`

cheers..

[Sheldon Hearn (sheldonh)]

The same work-around resolves another mouse pointer issue in a VirtualBox guest (using virtualbox-guest-dkms and virtualbox-guest-x11), where the mouse point is present, but is offset from where clicks are registered.

It's most obvious in a terminal window, where the click offset is -1,-1 character from the mouse pointer.

[Dmitriy Geels (dmig)]

I think, I found better workaround: after I changed lightdm configuration using 'lightdm greeter settings', I don't face this bug anymore

[Jens Herrmann (bugs-u)]

What exactly did you change in the 'lightdm greeter settings'? Ich changed the background from wallpaper to color and still face this bug.

[Dmitriy Geels (dmig)]

No, that's not a workaround. Bug appeared again after several hibernate-resume cycles.
I never seen this bug with xubuntu 15.10, kernel 4.5 from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and latest Intel graphics from 01.org. But it appeared after installing 16.04.

I'll try latest kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/, may be it helps.

[Donmatas (elcorreodematias)]

I made a launcher in the panel with the command "xset s activate" and it works for me.

[Kevin Brubeck Unhammer (unhammer)]

Even with xscreensaver instead of light-locker, there are times when the cursor disappears on a *fresh* login (not after locking/suspending). I'm trying light-locker again now, and using the workaround from https://linux4tw.wordpress.com/2016/05/25/disappearing-mouse-pointer-in-xubuntu/#comment-47 which at least requires no user-input to keep the cursor.

[Henry J. Douglas (cyberdoug42-deactivatedaccount)]

In this laptop, the mouse cursor is NOT affected if I let the computer lock itself when idle. It will only become invisible if I choose to lock it immediately OR lock it when closing the lid.

[Dave (dv0424)]

Work around:

I'm running a Lenovo Flex 3 with Xubuntu. The problems shows up as stated above (locking, sleeping, etc).

After sleeping mouse is missing, however you can tell when it is moved over the whisker menu because the menu changes as the mouse-over event occurs.

After sleep log in

1. Move mouse to Whisker menu (for me top left corner of screen)
2. click and open Whisker menu - don't move mouse
3. Start typing (I just type "Sett")
4. Move mouse down menu, and back up over text box.

I've done this at least a dozen times now, and this seems to work for me every time. Some things I noticed is that if I open the menu and move the mouse prior to typing, it only works about half the time, if it doesn't work I close the menu then duplicate the steps above and it works.

[Mikehl (ms-doss)]

@Dave

I juste tried and this "workaround" also works for me.
I don't know wich is better...CTRL+ALT+F1 or this one ahah !

I find that once this happens, if I move the cursor to a second monitor and back it reappears.

[Sb (sb56637)]

I'm also facing this issue with light-locker and Intel graphics on openSUSE Tumbleweed. It does not occur on openSUSE Leap (4.1 kernel), so it is a regression.

[Dietmar May (dcmay-f)]

I'm running Ubuntu Gnome 16.04, with gdm3. I do not have light-locker or xscreensaver installed.

This happens almost every time that I fast switch to a different user. Pushing the mouse to the upper left corner (which shows the Activities Overview) and pressing Ctrl makes the cursor show up - every time. Pressing Super (which shows the Activities Overview) and nudging the mouse makes the cursor show up - every time. Nudging the mouse and then pressing Super makes the cursor show up.

This combination - in just about any order - seems to reliably make the mouse reappear:
 * Move the mouse
 * Press a key
 * Show the activities overview

I'm sorry, I got a little ahead of myself there.
Parole is the standard video player that Xubuntu comes with.

Now that I tried it a couple of ways, the video player brings the mouse pointer back, even after unlocking the screen (by simply bringing the application to the foreground). VLC shows the same behavior as Parole.

The video player workaround works with mpv, too, but apparently I have to move the cursor over the player window. Just starting and immediately stopping mpv was not enough. My mpv configuration uses OpenGL/VAAPI output.

[Eyal Zekaria (eyal-ez)]

BTW, I'm also experiencing a different error besides this one which I couldn't really find a bug ticket for, maybe someone else here also has it?

Sometimes when turning on the laptop (opening the lid) after it has been suspended, I'm getting a black screen with back light, but nothing else. Tried all key combinations I could think of, nothing helped. When that happens I have to shut down the laptop altogether by pressing the power button for a few seconds and then turn it on again.....

It happens both when suspending from power option and when closing the lid and suspending.

I think this bug is not related to Intel. I'm on nvidia nuveau(default) driver and have exactly the same problem on xubuntu 16.04. Everything was okay on 15.10. Wokaround Ctrl-Alt-F1 -> Ctrl-Alt-F7 works for me also. If i change driver to nvidia(proprietary) bug goes away. But this driver makes video in VLC "segmented".

[sudodus (nio-wiklund)]

I agree with peerus (comment #139). I suspect that this bug is related to another program package, but I do not know enough to be able to suggest which package.

I have problems with graphics with a non-intel graphics chip. It turns pale (almost completely greyed out), and after switching to another virtual screen and back again, the graphic rendering is good again. See this link

Has someone taken the patch (or rather revert) that was linked in the freedesktop bug entry and tried to apply it to the Ubuntu package? (That appears to be this commit: https://cgit.freedesktop.org/xorg/xserver/commit/?id=b04767c84deafc44993723add4b1c5163fc11711). I have no experience in how the Ubuntu distribution is run, but is it out of the question to apply this as patch on the Ubuntu side to finally fix this?

I notice that already in my surroundings, several not-so-proficient users are severely affected by this. (One has switched back to a rather old Windows installation because the key combinations of the workaround are apparently too difficult to remember.) So this is keeping me from updating to 16.04.

pmow, you could give them the below script first, which does the VT-switching automatically. It's worked fine for me for quite some time.

Bug repro'd here after upgrade to 16. Dell Latitude E5530. I solve it by hitting CR in a terminal after login, which I usually have up. If not, I can use the invisible pointer to launch the terminal.

Thank goodness you told everyone. With it only affecting 350 other people, your particular workaround is of critical importance.

elementary OS 0.4 Loki Beta (Ubuntu 16.04 based) is also effected.

[Grorco (grorco-linux)]

I'm running 16.04 on a HP envy 17t I only have the problem if I lock the screen, then hit switch user after that logging back in will cause mouse to disappear. I can get it back quickly by ctrl+alt+t to get a terminal and typing sudo then hitting the enter key.

[Mario Steele (eumario)]

To me, what it seems to be the problem, is that Lock Screens, and Login systems, such as GDM, or LightDM, or Pantheon's is utilizing VTs to display Login, and switch between users / lock screen and log back in. Which seems to be solved by resetting the Virtual Terminal, either through a chvt between 1 and 7, or bringing up / having a terminal open, and issuing some command that causes a line reset to which the Mouse Cursor is allowed to be displayed again. That's what it seems to me anyways.

Hello everyone and future posters.

In order to keep the noise to a minimum, if you wish to +1 this bug, you can use the top button which asks if this bug report is affecting you. The switching terminals workaround has been confirmed time and again so reiterating it adds absolutely no value.

However, it has been observed that switching the version of the Intel graphics driver fixes the problem, so if you want to be truly helpful, use the git bisect feature and try and identify which commit fixes the issue.

[Shawn B. (slooksterpsv)]

I'd be willing to try the got feature and apply to locate the fix. Can you provide more information on how to accomplish that? Such as the URL to bisect from, a list of potential revisions to try, etc? I've used got to clone, branch, commit, and sync but that's it. I'd love to track this bug down and squish it.

Finding that the yakkety package updated recently I installed that on xenial, appears to fix the cursor visiblity issue on suspend and/or lock.

[José Jorge (mexchip)]

I am running Xenial on an Inspiron 14 laptop with Intel video.

As per requested in the xubuntu-users mailing list, I installed the xserver-xorg-video-intel deb from the yaketti packages, both:

* Test that following a return from suspend and logging that the cursor is visible.
* Test that following a lock and unlock that the cursor is visible.

work fine with the yaketty package.

Removing the yaketty package and going back to the xenial one makes only this one work:

* Test that following a return from suspend and logging that the cursor is visible.

[R00lf (rodolphe-debi)]

I am running Xenial on a acer V3-112 (Celeron n2840) laptop with Intel video and have this bug (cursor loss on suspend/lock).

I've just installed the xserver-xorg-video-intel deb from the yaketti packages (because of flocculant mail on xubuntu-users mailing list).

- return from suspend : the cursor is visible.
- lock and unlock : the cursor is visible.

so, no more bug with the yaketty package

Thanks

This may already be solved or known as well however I'm having the same issue. I'm using Ubuntu 16.04 at its base (its Ubuntu Gnome 16.04). I'm using a script to put the machine (i'm on a desktop not lappy) to sleep upon a keyboard shortcut and once it "awakes" I can unlock the machine but the cursor is missing (right click shows the default nautilus menu however, but no cursor) however if I have an open window (or if i open a terminal via a shortcut) already i.e: firefox and alt+tab (or super+tab in my case) the cursor displays. Very odd. I cannot replicate any other time other than resuming from sleep. I've ran a dist-upgrade, normal 'upgrade' still no avail, Any thoughts?

[Mario Steele (eumario)]

I have tried both the ppa:oibaf/graphics-drivers repo, and the Xorg.conf.d method on my Asus S550CA, with Intel Ivybridge, and now the issue seems intermediate. It'll sometimes unlock, with the cursor visible, and sometimes it'll not show the cursor till I have issued the chvt 1+7 script to have it re-appear. So, between the two, there's something that is making it work sometimes, and not other times.

[Mario Steele (eumario)]

Slight amendment to my last comment. The issue is resolved when manually locking the screen. The cursor will come back each time. The issue remains however, when using the Automatic screen shutoff of the OS, to shut off the monitor after being idle for so long. Switching to 5 minute idle before turning off the monitor helps make it easier to see the issue. However, when Suspending the system, and manually locking, the cursor does return after unlocking the screen.

[peerus (tsifra)]

I've also updated from ppa:oibaf/graphics-drivers and everything work perfectly now. I have two notebooks. One on nouveau (nvidea), other on intel. Both are solved. So i believe problem is not related directly to drivers.

@Sean

Thank you for the patch. This looks too big to review to me, although other sponsors may disagree. So, though I don't usually work in the desktop area, I disagree with your statement "Regression potential here seems minimal". This might be why some other sponsors have been unwilling to touch this. Can I suggest that you bisect the changes to find the single fix needed to solve the problem, and then submit a debdiff with just that change? SRU policy says that to minimise regression risk to users, we should backport a minimal fix where possible.

This might not apply if there is a bigger picture plan to update the Intel driver, but I presume there isn't one since this bug has languished for a while.

HTH.

The beginning of this page says issue is fixed for xserver-xorg-video-intel on Ubuntu, but there is no obvious link to the fix or instructions.
I am running Lubuntu 16.04 and my xserver-xorg-video-intel version was 2:2.99.917+git20160325-1ubuntu1 (it is a one, and not an "L" in front of ubuntu) and after doing an update in "Synaptic Package Manager" it still said this was the latest version, so I searched for the version you see if you hover over "xserver-xorg-video-intel (Ubuntu)" which is 2:2.99.917+git20160706-1ubuntu1 and found it here:
https://launchpad.net/ubuntu/yakkety/+package/xserver-xorg-video-intel

However, this is for 16.10 and this bug is reported for 16.04, but I still downloaded this and installed by running commands:
sudo dpkg -P xserver-xorg-video-intel
sudo dpkg -i xserver-xorg-video-intel_2.99.917+git20160706-1ubuntu1_amd64.deb

I then rebooted and tested and issue appears to be fixed.
I hope this helps others.

[richo (richo67)]

Please excuse me if my comment has no added value for you. I never did report any bugs on Linux. I tried to report disappearing of the mouse pointer on Elementary OS 0.4 Loki. (Linux hpbook 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64)

I have got here following suggestion that this may be the bug I try to report.

I am experiencing it when waking up my notebook from Sleep mode. The workaround switching between vt1 and vt7 restores the mouse pointer.

I wonder how developers of Elementary OS will know about fix for this issue?

Hi,
There are a few notes from my side.
Proposed workaround with adding adding configuration file for XOrg may affect re-draw speed and should be used carefully (tested on Xubuntu 16.04.1).

Moreover, the latest (5th) update for ubuntu 14.04.5 contains this issue (4th works like a charm). The second proposed workaround with installation of yakkety's does not work due to unsatisfied requirements.

[Yury Krasouski (krasoffski)]

Moreover, if you would like to build intel driver manually, you can use steps bellow (your own risk, I checked only for 14.04.5 and 16.04.1).

$ git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-intel
$ cd xf86-video-intel

$ docker run -v `pwd`:/build -i -t ubuntu:14.04 /bin/bash
# apt update && apt upgrade && apt install build-essential dh-autoreconf xutils-dev xorg-dev git
# ./autogen.sh
# make
# exit

$ find ./ -name intel_drv.so
$ sudo apt purge xserver-xorg-video-intel*
cp ./src/.libs/intel_drv.so /usr/local/lib/xorg/modules/drivers/

You can install intel driver from repo using:
$ sudo apt purge xserver-xorg-video-intel-{VERSION}

P.S. May be it makes sense to create Dockerfile :-)

[Kev Bowring (flocculant)]

@ krasoffski

I have just :

Installed trusty 14.04.4 > no cursor issues

Updated and ended up with 14.04.5 > no cursor issues

enabled -proposed and updated > no cursor issues

Only issue I get is if I let upgrade to 16.04.x take place, issue is then totally expected.

Not sure why you are seeing what you are but given you think it's on 14.04.5 probably a new bug, please re-report it and see if you can get others to confirm on 14.04.5.

[Yury Krasouski (krasoffski)]

Sorry for spam, some additional notes (not necessary):

# ./autogen.sh --enable-kms-only --enable-uxa

[Jan Koci (cicindel)]

#190 because it doesn't affect vanilla ubuntu? only derivatives like xubuntu and elementary are affected

[d3b null (d3b-null)]

According to #14 (or #38) in https://bugs.launchpad.net/ubuntu/+bug/1573454 it happens in all Ubuntu flavours, but I did not test myself. I am using xubuntu too.

If it is affecting all ubuntu versions with intel graphics that would be a very important bug and not getting this fixed after months, in a LTS, is a good enough reason for users to sadly stop using ubuntu.

[Romano Giannetti (romano-giannetti)]

Hmm. Using Ubuntu Gnome 16.04 here, intel graphics, no bug. On another laptop, with Xubuntu, it happens.

I think is more screen-locker related that desktop-flavor related.

[Yury Krasouski (krasoffski)]

As mentioned before, this issue might be related with light locker. After removing this one and installation of other screen locker the issue disappears.

[Adam Conrad (adconrad)]

Hello Kenneth, or anyone else affected,

Accepted xserver-xorg-video-intel into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/xserver-xorg-video-intel/2:2.99.917+git20160325-1ubuntu1.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Following idea from comment #40, if bug still exists it's enough just to press Ctrl+F7, to push display refresh.

But Lubuntu 14.04 LTS uses light-locker

Test to do...

sudo apt-get install gnome-screensaver
sudo apt-get install xscreensaver

Ctrl+Alt+T

light-locker-command -l ----> Mouse cursor lost

killall light-locker

ElementaryOS 0.3.2 Freya (all updates up to sat 17 sept 2016)
running with TLP (http://linrunner.de/en/tlp/tlp.html)

Recently started having this issue too. When returning from lock screen:
On the lock screen the mouse cursor is visible and working. After successfull password, the mouse still works but the cursor pointer is not visible.

Notes:
  Recently I started to, ocasionally, connect to TV via display port (don't know if it is related)

Workarounds that work for me:
  - shutdown and restart the computer - this is tedious and disruptive, but works.
  - press fn+f7 (key for changing to external display. Since there is no external display the screen just flickers once) - THIS IS EASY and fast, basically, the reason for my comment here.

I'm with ElementaryOS Freya.
Bug is still there

Is it because the fix is only available on xenial-updates, and still not present in trusty-updates?

I'm using ElementaryOS Freya but now with two monitors and discovered that if you move the "hiden" mouse between the monitor the mouse cursor reappear.

I've tried to install the OIBAF drivers but nothing changed. The problem persists until now.

[Grant (gsupp)]

Same issue as reported in comment #244. The fix release for elementary OS only applies to version 0.4 Loki. Those of us running 0.3 Freya with the Trusty LTS Enablement Stack have not received an updated xserver-xorg-video-intel-lts-xenial:

$ lsb_release -a
No LSB modules are available.
Distributor ID: elementary OS
Description: elementary OS Freya
Release: 0.3.2

According to comment #203, the fix is in xserver-xorg-video-intel version 2:2.99.917+git20160325-1ubuntu1.1 (versus 2:2.99.917+git20160325-1ubuntu1). Hopefully this package will be updated in Trusty, so distros such as elementary OS Freya can benefit.

As mentioned before, the workaround is switching ttys with Ctl-Alt-F1 and then back with Ctl-Alt-F7.

The use of this driver is discouraged if your hw is new enough (ca. 2007 and newer). You can try uninstalling this driver and let the server use it's builtin modesetting driver instead.

About my comments #261 & #262

I have problems with Google Chrome if I remove xserver-org-video-all (in my case xserver-xorg-video-all-lts-xenial) packages. Chrome works very slow and many times I'v got error application at startup.

Reinstalling the packages solves the problem with Chrome.

I read at some places that graphics acceleration can cause problems using Chrome, http://www.pcadvisor.co.uk/how-to/internet/how-turn-off-gpu-hardware-acceleration-in-google-chrome-3605455/

It would seem this problem still exists on trusty 14.04.5 LTS:

Hi guys

Does anyone know if some kinda-new fix or workaround was released for Freya in these latest months?

I've same versions/config/OS as @ledel (previous post)

[Josep Pujadas-Jubany (jpujades)]

We migrated all the computers to Lubuntu (Ubuntu + LXDE) 16.04 64 bit. The problem is solved for us.

We had the problem with Lubuntu 14.04 32 & 64 bit with kernel enablement stack.
( https://wiki.ubuntu.com/Kernel/LTSEnablementStack )

We can't test this with 32 bit systems because we haven't them anymore.

Also affect Ubuntu 18.04.

I am still seeing this with Mint 18.3 and 19 on at least 4 different PCs but with nvidia graphics. Is there a fix somewhere?

[Steve Baker (y9a7s7tjd2-s1eac-si9yrl01qs)]

I'm seeing something like this on a 32bit Acer laptop - with Intel graphics - running Kubuntu 18.04.1 - it's been doing it for quite a long time - but it's still a current bug - I did a full apt upgrade/update just today.

When the machine awakes from a sleep (eg with by closing and opening the lid) the mouse cursor is gone - and the whole screen below the mouse position is white. So as you move the mouse up and down and it covers and uncovers the entire screen. You have no way to tell where the X position of the mouse is - but it does seem to work and you can still click on things.

Switching to a different virtual console and back again using Ctrl-Alt-Fn seems to fix it...until the machine goes to sleep again.

Seems like maybe some piece of graphics state isn't being properly saved and restored.

[Qianqian Fang (fangq)]

Had this issue occasionally last year on Ubuntu 20.04, but now every single time in the past week after my laptop wakes up from sleep.

Laptop is an Asus TUF F15 gaming laptop, with an NVIDIA 2060 GPU (hybrid graphics with Radeon Renoir GPU). CPU is an AMD Ryzen 7 4800H. NVIDIA driver 460.91.03. Ubuntu 20.04.3 LTS with Xfce 4.14.

Kernel version 5.6.14-050614-generic, dual monitors, one connected to the HDMI port from the USB-C adaptor (DP-0, connected directly to the NVIDIA GPU), and the other one connected to the HDMI port on the laptop (HDMI-1-1, graphics "pass-through" AMD Radeon GPU). see https://forums.developer.nvidia.com/t/ubuntu-19-04-doesnt-detect-my-hdmi-display/79577/80

When waking up, the DP-0 port (via USB-C, driven by NVIDIA GPU) does not have this issue, but the HDMI-1-1 port (via AMD GPU pass-through) loses cursor.

The workaround Ctrl+Alt+F1 followed by Alt+F7, as provided in #1573454 works. Looking for a permanent fix.

[Sam Osborn (samosborn)]

The permanent fix described by https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1568604/comments/261 works for me.

sudo apt-get purge xserver-xorg-video-intel*
sudo reboot

Note the poster of this fix has a follow up comment about the broader video driver removal also causing issues with Chrome, but I use Firefox so I havent seen any other issues removing just the intel driver.
